TL;DR Light-hydrocarbon blend for air intake and throttle body cleaning · fast-evaporating chemistry and a 360-degree nozzle. The back label has no explicit O2-sensor-safe or catalytic-converter-safe claim; "Safe for all component surfaces" is not a substitute. The SDS portal is down, so health scores reflect the no-SDS floor (Health 5.0/10 · NO SDS). Community evidence is too thin to rate above average (too few owner reports and no forum data). Use outdoors or with the hood up.
Remove the air intake duct, hold the throttle plate open, spray into the bore (5·15 seconds), and wipe with a microfiber. The light-solvent chemistry is consistent with fast, residue-free evaporation, but without review text or forum evidence there is no community record of before/after results or sensor-code reports for this product.
A reasonable choice for a port-injected throttle body if you already run Mag1 products. Skip it if explicit O2/cat-safe chemistry is required · the label makes no such claim and the SDS is not available to verify it. Skip it for GDI engines: aerosol TB cleaner cannot reach intake-valve carbon deposits; a dedicated GDI cleaner or walnut-blast is the right tool.
SDS unavailable · PPE tiers inferred from label ingredient chemistry only. Heptane and acetone aerosol in an engine bay can cause drowsiness; lungs-recommended PPE is the chemistry-inferred minimum. Eye protection advisable. The CARB compliance claim is a regulatory-accounting result (acetone is an exempt solvent) · absolute solvent emissions are still high. No Prop 65 warning on label. Petroleum-origin solvents are not biodegradable.
CarCareTruth scores Mag1 Air Intake/Throttle Body Cleaner at 5.1 out of 10 on the composite CCT score, with a health sub-score of 5.0/10. The CCT score blends real-world effectiveness, ingredient health impact pulled from the manufacturer's safety sheet, and environmental footprint against a published category rubric. See the methodology link on this page for the full scoring breakdown.
Per the Safety Data Sheet ingredient disclosure: Back-of-bottle label (mag1.com product page image, 2026-05-19): Heptane (CAS 142-82-5), Acetone (CAS 67-64-1), Propane (propellant, CAS 74-98-6).
